Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an apparatus for uniformly manufacturing monolithic refractories such as castable refractories, plastic refractories, and spray materials.

[Prior art]

Conventionally, various types of methods for uniformly mixing monolithic refractories have been known. For example, a mixture of 500Kg to 1ton/batch of raw materials is 25
Divided into ~40Kg/bag. However, when dividing one batch of products into bags, not only is segregation aggravated, but also because the mixed product is stored in a tank, segregation occurs again when it is loaded and taken out. You can't prevent Shion. Therefore, it must be considered that variations in quality occur among bags as final products, regardless of the degree of variation.

Furthermore, it is extremely difficult to uniformly mix a large amount of blended raw materials, and a large amount of dust-generating substances is also inevitably required. Although it will be collected using a powerful dust collector, there is a high possibility that important fine particles, especially special additives, will be removed. Therefore, there is a risk that the blending ratio will change, that is, the quality will deteriorate.

Furthermore, it is necessary to dispose of the raw materials remaining in each raw material hopper after adjustment, but conventionally, a separate recovery circuit for this purpose has been provided or the residual raw materials have been removed from the hoppers manually. However, this resulted in high equipment costs, and in the case of manual labor, the workers were forced to perform unhygienic and harsh labor.

[Purpose of invention]

The present invention provides an apparatus for uniformly manufacturing monolithic refractories that can efficiently produce monolithic refractories having a uniform composition, and can also eliminate residual raw materials effectively and at low equipment costs. The purpose is to

[Structure of the idea]

The present invention connects a plurality of large-volume hoppers to a corresponding number of large-volume automatic weighing machines through a branch chute consisting of a chute with a feeder and a chute without a feeder, and discharges the large-volume automatic weighing machines to the lower end. Connecting to the upper end of a common chute having a switching feeder whose position can be selected, and connecting the discharge port of the selectable switching feeder to a mixer during mixing and to a raw material recovery device when recovering raw materials remaining in the hopper; A uniform production device for monolithic refractories, characterized in that a small-volume hopper is connected to a small-capacity automatic weighing machine via a feeder, and connected to a mixing machine by a chute attached to the small-capacity automatic weighing machine. This is related.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

FIG. 1 shows the manufacturing process from raw material arrival to product shipment, and FIG. 2 shows an overall explanatory diagram.

According to these drawings, each raw material is transported by truck
The materials are transported in container bags 2 (1 to 1.5 tons) and temporarily stored in a temporary storage area 4 on the upper floor of the building 3, for example on the third floor, using a necessary lift device 5.

On the same floor, there are a required number of raw material hoppers 6 arranged in parallel for supplying the raw materials by particle size, type, etc. Accordingly, the container bags 2 are brought in by the ceiling hoist 7, and each raw material is delivered to its own location. Pour into hopper 6. It should be noted that materials such as binders that are used in small amounts are supplied to a hopper 8 that is separately arranged in parallel. The hopper 6 of each raw material is transferred to a large quantity automatic weighing machine 1 through a branch chute 9 consisting of a chute with a feeder 10 such as an electromagnetic feeder and a chute without a feeder.
It is connected to 1. Further, the hoppers 8 are similarly arranged in the automatic weighing machines 13 for small quantities via feeders 12 such as electromagnetic feeders.

In this configuration, the raw material from the hopper 6 is supplied to the large-volume automatic weighing machine 11 through a chute with a feeder 10 during adjustment packaging, and is supplied to the automatic weighing machine 11 through a chute without a feeder 10 during residue removal. 11.

A feeder 14 is located directly below the discharge port of the automatic weighing machine 11.
A common chute 15 is provided, which is connected to a switching feeder 16 such as a swing feeder. The discharge port 18 of the switching feeder 16 is connected to a small-capacity mixer 19 provided directly below it.
It is opened above. Therefore, the hoppers 6 and 8 are selected depending on the raw materials to be blended, and cutting and weighing of the raw materials to be blended are automatically performed in the operation room.

When the appropriate amount is discharged through each automatic weighing machine 11, 13, it reaches the switching feeder 16 via the chute 15, 17, and is combined on the mixer 19.

The mixing machine 19 controls the amount of bagging (for example, a 25 kg bag).
Because raw materials will be supplied according to the
Here, the mixed raw materials are sufficiently uniformly kneaded, and then all of the mixed raw materials are directly put into the empty bag 21 directly below the discharge port 20. 22 is a bag feeding device;
The product 23 packed with mixed raw materials is sent from a desired conveyor 24 to a palletizing device 26 after the opening is sealed.

In the palletizing device 26, the automatic loading machine 27 arranges the required number of bagged products 23 side by side,
These pallets 29 are stacked. The palletized products are stored in the product warehouse in this state, and are shipped in palletized form as needed.

Next, the raw materials remaining in each hopper 6 after the adjustment and packaging work are removed from the hopper 6 via a chute that does not have a feeder 10, and then quickly transferred to the common chute 1 via a large-volume automatic weighing machine 11 and a feeder 14.
5. Thereafter, the rotating feeder 16 is rotated and connected to the raw material recovery device 30, and the raw material is fed into the device.

In addition, according to this apparatus, the process from cutting out the mixed raw materials to bagging can be centrally controlled using, for example, a microcomputer and a card reader. The control system diagram in this case is shown in FIG. 4, and the card checking system and automatic operation system are shown in FIGS. 5 and 6, respectively.

[Effect of idea]

As described above, the present invention can achieve the following effects.

(b) Since the method automatically discharges, weighs, and mixes the raw materials to be blended in each bag, there is less chance of segregation or segregation occurring than in conventional methods, and it is possible to mix a small amount using a mixer. Therefore, the adjustment of the monolithic refractory is sufficiently uniform, and therefore, the quality of the product can be maintained at a high level with little variation.

(b) The amount of dust generated can be significantly reduced due to the production of bagged units, making it possible to effectively prevent pollution.

C. Since the capacity of the dust collector can be small, there is no risk of removing important fine particles more than necessary, and the quality will not change.

D. Since it is possible to adopt a centralized control system, the number of workers can be reduced, labor can be saved, and rational production can be achieved.

E. Since the adjustment bagging of the monolithic refractories and the removal of residual raw materials can be carried out through the same route, equipment for this purpose can be provided at low cost, and the residual raw materials can be automatically removed.
